BED.

Specification of Letters Patent.A

Patented Aug. 24, 1915.

Application led May 18, 1914. Serial No. 839,250.

'. other uses where it is desired that the occupant shall lie at any desired angle-With respect to the horizontal, or that 4any part of'v the body of the occupant should be lowered or elevated with respect to his main body.

AMyinv'fention provides .means for insert- .ing a bed-pan, hot-Water bottle or the like under the occupant of they bed without raising or otherwise moving him, and the entire 'bedl maybe rotated in its horizontal plane, raised orlovvered as desired Without disturbing the occupant.

The invention will be more fully described in thel following speci'cation, illustrated in the accompanying drawings and Apointed out 1n the appended claim.'

`In the dravvings,Figure 'is a side elevation on my improved bed with one end partially lowered. Figl`2, is a plan view of the same with all but a fragment of the springs and spring supports broken away. Fig. 3 is a partial sectional elevation of o ne half of the bed'taken through the partially open joint shown in'Fig 2. Fig. 4 isa sectional plan view on the line li/--Jy of Fig. 1.

Referring now' more particularly to the drawings, refere'ncenumeral 1 designates a support lhaving legs 1a .extending radially fromit, and -which may be provided with ca stersV such Aas indicated at 1d. Support is of` hollow cylindrical form, as

shown, the interior of said support being in 1 dicated at 1". The bottom end of the said support is closed with the exception of the small/ vent holes indicated at 1, which are provided -to allovv the slow .escape of air from the interior of the support 1, as will be presently explained.

2, designates a plunger having the' annular groove 3 into whichthe pins 4; project, said pins being secured tb the forked arm 5 of a lever 6 which is pivotally mounted upon the projecting 7 extending from the sup-l portsl`-,fby means of a pin 8. T he'supp'ort 1 .channeled as indicated at 2, to allow 'werking space for the arms 5.

The said.

threaded at each' of their ends.

6, indicates a lever which is provided at one of its ends with a foot-piece 6a and at its opposite end are teeth 6", 'any one of said teeth being adapted to be engaged by the point 9a of the pavvlA4 9 ivhich is pivotally supported upon the cylindrical supportll, by means of a pin 10. The said pavvl 9 is held into engagementjvith-any one ofthe teeth 6b bymeans of a rod 11, collar 12 and spring 13, the said spring acting against the said collar(held to the rod 11 by a screw 11) and an arm 15 through which the rod' 11 passes, the said rod, terminating in a handle portion. 16. -Tle plunger 2 terminates in a forked head 17 through which a shaft 18 passes. Mounted upon said shaft are links 19, 19a, 20,20, 21and 21, and to the said shaft collars such as indicated at 22 are firmly secured. Passing through the links 19 and 19 and the head extensions 19", which.

-32 pass through the links 25 and 26 and 25a and 26", respectively, and the. foot-piece extensions 33 and 34 and 33a and'34, respectively and are equipped, similarly 'to the shaft 27. The said foot-piece'extensions are all built `rigidly with the foot-pieces 35 and 35 respectively. The ends of the links 19, 19a, 20, 20a, 25, 25a and 26 and 26a, and the head and foot extensions 19", 30 4and 30, 3l and 34a, which come into contact with each other, have their faces scored radially, .as at 36 (see Fig. 3). The shafts 18 and 23 are and 30 and 31, and 32 are.l threaded on their outer endsfonly to receive the hand nuts 37 Vwhich force the compression springs 38 agamst the various links, which links areheld from sliding along their shafts by the .collars 22 and 24 attached thereto. Onthe shafts` 27, 30, 31 and 33 the inner pairs of links are held in Vcontact by means ofthe hand nuts 37 acting against the springs 38,

the saidk springs acting against `the outerpairs of the links which bear against the tubes 29 loosely fitted over the shafts. The -inner pairs of links are thus securely held Shafts 27 l I between-the tubes '29 andthe collars 28. The mattress is in convenient sections, as 1s plaiiulyI shown, and each section is comp o'sed o `springs 39a and padding 39", and .thejvarious sections of the said mattress rest I loosely upon supports l0 which ,are carried' a sections A and B, as shown at the-foot-end i of the bed,'it is possible to elevate either onev 'uieans o f forked legs l0 vvhich straddle the various links and are integral with the support 40.

ronr the above description'it believed thatthe construction and operation of my device will be `fully understood by others skilled inthe art. It is obvious that by looseningthe hand nuts on any particular shaft that that portion of the bed thus looscned from. the scored face of the links will 'be' vto be vrevolved manually about its shaft as a center to any desired ,posit-ion,`

lBymiearis` of a division of a part of the bed alonguits longitudinal center into separate of the'said divisions and ydepress the other.

.rIt isfalso obvious that by pressingdovvn- )vardlyupon lthe foot-piece 6? thaty the lever- 6 will operate. about its'pivot 8 causing thev pin-4, acting. in the annular groove 3, to force by the impounded air Within the interior 1" ofA the lsupport` l, theair slowly escaping through the small vent holes lc. i By releasingthe handle 16 at any desired time th'epavvl `point Qavvill again engage some one'of the-teeth 6", thus preventing farther downwardkniovementof the plunger 2. Due to theannular groove-3 and the plunger 2,

:which is 'cylindrical'in cross section tov fit theinterior lb of the support 1, and the projecting pins 4., itis clear that the said plunger and all its connected parts' are to be.

manually .revolved about the vertical axis of the said plunger, It is also clearthat any one, or more, sections of the mattress 39 may be drawn from under* thel occupant 'of the lbed-,-Without Likewise, any 'y,onefoffthesectionsof the ymattress 39 may be replaced by simply thrusting a fresh section under the occupa`nt,-- This feature ot my in- `Water bottle, 'or'the like beneath the patient all thatis-neeessary istoremove a section.

ofthe mattress, Which-provides a space for such bed-pan, hotwater bottle' or the like. From the iforegoiungy itis plain that my improved bed W-illobviate -much of the vvork heretofore necessary in caring for a patient, and at the'sa'lne itiine provide .a much more comfortable ,bedthan has heretofore been .lnuovvn-inthe.art.'

1 have vshown and described 'a 4particular form of embodiment o fmy invention but am v entifni'l .is .of obvious advantage 4because -when it isdesiredto placev a bed-pan', hotaware thatma'ny minor changes therein will f readily suggestxthcmselves to othersskilled A inthe'art lvv'itlmut departing from the and scope of theinventiom and I'lthereore desire tarid beile'- limited te the'y orm shown 'and described.V

.Having described--iny invention, what? I In an .adjustable `bed, 'th'e eombinatiom of a rigidl hollow cylindrical' support, a rota table and; vertically movable' plunger fitted ,within the said support andl to fthe' upper, end of which is. pivotally mounted the bedrame, the said-plunger annular groove there around, .a1 forked lever' pvoted upon the said supportlthe'terminals of which fork enter the said annular-groove, means foi-'holding the said lever in its various ad justed positions, said-means including 'teeth upon the said lever, a coperating pawl upon the said support and a sp ,controlled rod.
